Foreword

Appendix A of this standard is a normative appendix, Appendix B is an informative annex. The standard proposed by China Machinery Industry Federation. This standard by the National Electrical Instrument Standardization Technical Committee (SAC/TC104) centralized. This standard was drafted. Harbin Electrical Instrument Research Institute, Shanghai EF Electronics Technology Co., Ltd., Zhejiang Dongfang Electrical Co., Ltd. The main drafters of this standard. Sit Jin, Liuxian Cheng, Cheng Feng.

Introduction

Direct acting indicating analogue maximum demand meter is a thermal demand meter, double metal spiral heat deformation indicates a predetermined time The average current interval, and to promote resettable maximum demand pointer indicates the maximum demand current. In nominal voltage constant (or substantially no By varying) conditions also characterized the maximum demand power. The product has been in existence for quite a long time in the international arena, but no corresponding States Manufacturing standards, there is no relevant international standards, often demand period and a dispute between the manufacturer and distributor. In order to regulate such instruments Accuracy demand period, the measurement method of the demand period, power consumption, heat, meter pointer back to zero, demand pointer friction torque, etc. The problem, development of this standard. Thermal bimetallic series of instruments is reflected in measuring current is proportional to the rms thermal effects, thermal effects and current, so these instruments is essentially Table Effect of waveform distortion and the DC ripple of no communication. GB/T 7676 series of standards specified waveform distortion and DC ripple Movies Sound tests in this standard can be waived. In order to verify that the standard test methods in Appendix B provides a direct wave impact and ripple effects. Direct acting indicating analogue maximum demand ammeter

1 Scope

Direct Interaction Simulation 1.1 standard for measuring the maximum demand current in an AC circuit DC circuit or display electrical measuring instruments. 1.2 This standard also applies to have other electrical parameters (such as real-time current) measurement or control mechanism in the same enclosure, measuring electrical parameters or other Output control signal maximum demand meter. Measurement of electrical parameters or other control section shall comply with relevant national standards or IEC standards Requirements. 1.3 This standard does not apply to instruments with electronic circuits in the measurement circuit. 1.4 This standard does not include resistance to environmental protection requirements and associated test conditions. If necessary, by the manufacturer and user, from IEC 60068 Select the instrument close to the conditions of use of tests to verify resistance to environmental protection conditions. 1.5 meter standard dimensions are not specified, the instrument size requirements see GB/T 1242-2000 requirements.
